All callers of issue_probereq_p2p set the da parameter to NULL. Remove this parameters and the code that runs only for da != NULL. Tested-by: Philipp Hortmann <philipp.g.hortmann@gmail.com> # Edimax N150 Signed-off-by:

If we receive a disassoc message from an unknown station, we can drop this message immediately. Reorder the code to make this clearer. Tested-by: Philipp Hortmann <philipp.g.hortmann@gmail.com> # Edimax N150 Signed-off-by:

The OnDisassoc function hasn't got much to do if we're not working as an access point. Move this case out of the large if statement to simplify the code. Tested-by: Philipp Hortmann <philipp.g.hortmann@gmail.com> # Edimax N150 Signed-off-by:

Move the update of bBusyTraffic into the else branch. The if branch ends with a return statement, so bBusyTraffic will not be updated in this case. With this change in place, we can reorder the code and save some levels of indentation. Tested-by: Philipp Hortmann <philipp.g.hortmann@gmail.com> # Edimax N150 Signed-off-by:

Define a struct ieee80211_mgmt in the OnDisassoc function and use it to parse the addresses in the incoming disassoc message. This replaces some driver-specific functions for address parsing. Tested-by: Philipp Hortmann <philipp.g.hortmann@gmail.com> # Edimax N150 Signed-off-by:

Simplify the code to handle the case where we're associated to a station that is not in our list of known stations. We can simply exit in this case. This patch reverts the if-condition and saves one level of indentation. Tested-by: Philipp Hortmann <philipp.g.hortmann@gmail.com> # Edimax N150 Signed-off-by:

If we cannot allocate a struct wlan_bssid_ex in the OnBeacon function, we should stop processing the incoming beacon message and return. For kmalloc failures, the current code just skips the update of network and beacon info and tries to continue with the authentication. The update would set the encryption algorithm that should be used for the authentication. Tested-by: Philipp Hortmann <philipp.g.hortmann@gmail.com> # Edimax N150 Signed-off-by:

Do not process an incoming beacon message in the OnBeacon function if the beacon was sent by a base station other than the one to which we're connected. This patch does not modify the behaviour of the code. It reverts the if condition and returns if the beacon should not be processed. This is simpler than wrapping the entire processing into a large if clause. Tested-by: Philipp Hortmann <philipp.g.hortmann@gmail.com> # Edimax N150 Signed-off-by:

The update_sta_support_rate function takes a pointer to information elements and the total length of all these elements. Use our variables for pointer and length instead of calculating them manually. Tested-by: Philipp Hortmann <philipp.g.hortmann@gmail.com> # Edimax N150 Signed-off-by:

The update_beacon_info function parses information elements of a beacon message. It should take the pointer to the information elements and their total length, not the entire beacon message. Tested-by: Philipp Hortmann <philipp.g.hortmann@gmail.com> # Edimax N150 Signed-off-by:

Martin Kaiser authored
The process_p2p_ps_ie function parses the information elements of a beacon message and extracts p2p-related info. process_p2p_ps_ie does not receive a pointer to the information elements as one would expect. Instead it receives a pointer to the timestamp field in the beacon message. process_p2p_ps_ie increments this pointer by _BEACON_IE_OFFSET_ to jump to the start of the information elements (and decreases the buffer length accordingly). This is clumsy and hard to understand. Rewrite this such that process_p2p_ps_ie takes a pointer to the information elements and the total length of all elements. Check up-front that the total length is not negative. Tested-by: Philipp Hortmann <philipp.g.hortmann@gmail.com> # Edimax N150 Signed-off-by:

Define a struct ieee80211_mgmt in the OnBeacon function. Use it to replace one GetAddr3Ptr call. This is a tiny step towards making GetAddr3Ptr obsolete. Tested-by: Philipp Hortmann <philipp.g.hortmann@gmail.com> # Edimax N150 Signed-off-by:

issue_probereq_ex sends a probe request and retries if this fails. There's no point in making the number of retries configurable. Hard-code the value that's used by issue_probereq_ex's only caller.
